Interface Agents for Handling Fuzzy Descriptors in Information Retrieval

In this paper, it is assumed that a user interface is a collection of agents that assist the user in performing information retrieval (IR) tasks. The design of such agents requires a better understanding of IR human capabilities and tasks. User queries are usually vague and incrementally refined. Librarian agents help users to better define and refine their queries. They transform human-based fuzzy queries into system-manageable queries. In addition, users can refine queries according to appropriate feedback. A first attempt at the design of interface agents in IR is proposed, as well as examples of such agents.
